SAFETY CAR-STOVE.

SPECIFICATIQN forming part of Letters Patent No. 398,880, dated February 26, 1889.

Application filed May 18, 1887. Serial No. 238,038. (No niodeli T0 aZZ whom it may concern.-

Be it known that I, Alain-in ltnnsnot Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Safety Car-Stoves; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to the stoves employed in railroad-cars for heating purposes, its object being to improve the construction of the safety car-stove heretofore patented by me on September 16, 1873, No. 143,867, and December 19, 1882, No. 269,3;l. In these car-stoves as covered by my previous patents a waterreservoir is arranged above the stove, this reservoir communicating by a valve with the fire pot of the stove, and the valve being held closed by a cord which extends to the top of the car, to the side and end walls thereof, to the platform, and is connected with suitable tripping apparatus located in such position that itwould be operated in case the car was derailed, and the apparatus was so arranged that 111 case of accidents-by a colhipse of the car, the breaking of the platform, or the dera1l1nent-this cord would be slackencd and the lire therein, the apparatus being so an ranged that in case of accident the fire would be extinguished in this manner before the car I could turn over, and consequently all danger from tires ignited by the stove located within the car was overcome.

My invention consi. is in certain improvements and combinations of parts, all of which will be fully hereinafter described.

To enable others skilled in the art to employ my invention, I will describe the same more fully, rcfcrrin to the accompanying drawings, in which- Figure 1 is a longitudinal central section of a car-stove and the end of the car, illustrating my invention; and Figs. 2 and 3 are detailed views illustrating the operation of the valve apparatus.

Like letters of reference indicate like parts in each.

The car (It is of the usual or any approved construction, having the roof (1, the end walls, 0, the bed or floor (7, and the platform d. Resting on the floor (Z is the car-stove which can be made of an y approved form, this carst'ove having the tire-box e and the smokefluc e leading from the upper part thereof to one side of the stove and thence upwardly through the roof 11.

Above the top plate, c of the stove is the chamberf, which extends over the entire top surface of the stove, except at the center thereof, where the valve is located, and this chamber f is packed with asbestus or other suita' ble non-con ducting material, the non-conducting material being confined between the top plate of the stove, the bottom plate, 7), of the water-reservoir and the outer wall, f, and inner wall, f said inner wall forming the central valvechamber of the apparatus.

The water-reservoir g extends above the stove any desired distance, so as to hold a sufficient body of water for extinguishing the fire, and is provided with any suitable fillingopening, as at Located within this reservoir g and the valve-chamber 72. is the valve apparatus, which consists of the valve 1', fitting within a seat, 7c, in the bottom-plate, h, of the reservoir, and guided in its movement by the valve-stein i, which passes through the bracket 72. within the valve-chamber 71, and the bracket Zwithin the reservoir. This valve 2' is formed of asbestus, compressed to shape, or similar non-3011ductin g material, which will prevent the passage of heat from the fire-box to the reservoir, and at the same time, as it is not liable to rust or disintegrate under the action of the water, is not so liable to stick in its valve-seat as the ordinary metal valve.

The top plate, c of the stove, which forms the base of the valvechamber 71, is perforated with a series of holes, which are preferably formed divergent, as described in Letters Patent No. 269,32l, above referred to, so as to spread the water which passes from the reservoir into the valve-chamber, and thence through the perforations into the firebox. The bracket Z is provided with the arms Z, in which the lever on is pivoted, this lever being connected to the valve-stem i by means of the sliding joint, as shown particularly in Figs. 2 and 3, and the lever having hung to its opposite end the weight n, so that as soon as the cord is released the weight will drop and draw up with it the valve-stem 1/, so rais 1 ing the valve "1? from its seat and permitting the passage of the water from the reservoir into the tire-box e of the stove. As,however,

the valve might stick slightly within its seat, i

by means of the sliding joint p, formed between the lever and valve stem, I am enabled to impart a jar to the valvestem and thus insure the opening of the valve.

The construction of the sliding connection between the valve-stem and lever is particularly shown in Figs. 2 and 3, the valve-stem having the lugs or pins 1-, which extend into the slots r, formed in the sleeve 01 plates 8, this sleeve or like plates being pivoted to the lever m, and when the valve is closed the extension on the cord forcing the lever down, so that the upper ends of the slots 0- press against the lugs r and force the valve to its seat; but as soon as the cord is released in any way, the weight a will draw down the lever 11:, and the slots r slide over the lugs r, until the lugs are caught by the bases of the slots, thus imparting a jar to the valve and insuring the opening thereof. The cord 2- passes upwardly through the reservoir and over the pulley attached to the roof I) of the car, thence over the pulley attached to the end wall thereof, and thence under the car, to be connected to the end platform and to the end of the lever apparatus, as described in Letters Patent No. 269,324.

The operation of my improved stove is as follows: The valve is closed downwardly against its seat by the tension on the wire cord or chain, as described in my previous Letters Patent, and the reservoir g is filled with water or other suitable liquid for eX- tinguishing the fire, and the apparatus re mains in this condition until through some accident the cord is loosened, either by the caving in of the roof or the end walls of the car or crushing of the platform by the derailment of the car, when this cord is, of

course, slackened, and as soon as the cord becomes slackened through any of these causes the weight n draws down the outer end of the lever m, which in turn draws up the 'valvestem f, imparting a jar thereto, as described, I and so causing the opening of the valve, and i the rod then passes from the reservoir to the i l fire-box, being spread over the body of the ignited fuel therein and quickly extinguishing the same, so that the fire is entirely extingnished before the stove could be turned i over or broken so that it would be liable to l ignite the body of the car. As the valve ap- I paratus is operated by a weight as contradis- 4 tinguished from a spring, it is evident that g the apparatus is always in condition for operation, and the objection heretofore found in 1 the employment of a spring for opening the valve, on account of the sprlng losing its 1 temper or tension on account of the long exposure of the heated water, is entirely overcome. At the same time by means of the joints between the valve-stein and lever I am enabled to impart a jar to the valve and insure its being opened. The body of asbestus I or similar non-conducting material between the stove and water-reservoir prevents the passage of any large amount of heat from the minimum the evaporation of the water within the reservoir, and the passage of any great body of heat through the valve-chamber is also prevented by the employment of the asbestus Wtlve, which prevents to a great ex tent the passage of heat through the upper part of the valve-chamber, and at the same time prevents the rusting and sticking of the valve which was found an objection in the ordinary metal valves.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. In safety car-stoves, the combination of the stove, the water-reservoir located above the stove, the valve closing comnnlnication between said reservoir and stove, the operating-lever, and a sliding jointconnecting the valve and lever, substantially as and for the purposes set forth.

2. In safety car-stoves, the combination of the stove, the reservoir located above the stove, the valve closing communication between them, the lever m, connected to the valve by a sliding joint, and the weight n for operating the lever, substantially as and for i the purposes set forth.

In testimony whereof I, the said ABRAM REESE, have hereunto set my hand.
